I liked this article. It was very useful. Thai Phan 11:26, 7 March 2007 (UTC)
does anyone have any uses for convex mirrors???

- Yep. As mentioned in the article, the passenger-side mirror on a car is typically convex. Convex mirrors are also used for telescopes and lasers.--Srleffler 02:19, 27 September 2006 (UTC)
Also for the security mirrors in 24-hour stores.--Cronholm144 14:07, 2 July 2007 (UTC)
[edit] Pictures and references
I am going to remake the pics on this article, just an FYI. Also this article needs some love in the form of a copy edit and references.--Cronholm144 14:07, 2 July 2007 (UTC)
[edit] I need help.
My dad told me to find out why a spoon gives an upsidedown reflection, I know the answer is on this page some where but I dont understand it.SzilardII 16:10, 12 July 2007 (UTC)
The spoon acts as a concave mirror, so it can actually reflect a real inverted image and a right side up non-real image, depending on the position of the reflected object. Go the the reference desk next time.--Cronholm144 22:57, 12 July 2007 (UTC)
[edit] New images
I must say that I dislike the new images. While they are pretty with their gradient-shaded mirrors, they have some flaws:
- In some of them, the mirror surfaces appear not to be spherical (i.e. the image does not show a circular cross-section).
- The radius of curvature of the reflecting surface must be twice the focal distance, centered on 2F. This does not appear to be the case in some of the figures.
- The curvature of the non-reflecting surface (and the fact that the mirrors taper to points at the ends) is bizarre. To better reflect real curved mirrors, the non-reflecting surface should either be flat, or should have the same radius of curvature as the reflecting surface (with center of curvature offset by the thickness of the mirror).
- The reflecting surface should be clearly distinguished from the non-reflecting surface in each figure. This could be accomplished by a bolder line on that surface. Having flat non-reflecting surfaces would probably be sufficient for the context of this article.

- I am sorry you dislike them, I followed in the form of what was there before. I can remake them again, but I am rather busy with real life right now. If you would like to change them yourself using inkscape, that would be really helpful. I will try to finish the new ones tomorrow, but if not, I won't be able to work again until next weekend.
